The subject disclosure relates to system and method to improve spectral efficiency for an optical fronthaul network in a mobile communications network.
Fronthaul refers to a communications connection among components of a cloud radio access network (C-RAN), a type of cellular network. The C-RAN generally includes centralized baseband units (BBUs) and remote radio heads (RRHs) at the access layer of the cellular network. Fronthaul includes standalone radio heads and baseband controllers located at remote cell sites. The radio heads are located at a cell site. The BBUs may be located at a central site to serve multiple RRHs. The network links that interconnect multiple RRHs and a BBU are called fronthaul. Fronthaul networks are generally optical networks. Passive optical networks (PONs) use optical splitters and point to multi-point topology for fronthaul communication. Wavelength division multiplexing (WDM) networks use optical signals to combine multiple signals at varying wavelengths for fiber optic transmission to enhance efficiency of fronthaul links.

The 5G core network 206 may include any suitable combination of network functions for serving other elements of the 5G mobility network 202. The 5G core network 206 may be formed from any suitable combination of data processing systems including servers, switches, and other devices. In some embodiments, the 5G core network 206 is formed using 5G network slicing. Network slicing is a network architecture that enables the multiplexing of virtualized and independent logical networks on the same physical network infrastructure. Each network slice is an isolated end-to-end network tailored to fulfill particular requirements of a particular application or function.
The components of the 5G core network 206 implement a number of discrete network functions. Such network functions include an access and mobility function (AMF), an authentication server function (AUSF), a session management function (SMF), a network slice selection function (NSSF), and others. The network functions enable communication among the components of the 5G core network 206 as well as communication between user equipment such as the UE device 204 and the components of the 5G core network 206. Further, the 5G core network 206 may provide one or more gateways to external networks such as the public internet for access by the UE device 204 and other devices. In some embodiments, the components of the 5G core network 206 are cloud native and may be distributed over multiple locations and accessible by one or more data networks.
The fronthaul network 208 includes a centralized unit (CU) 210 in communication with the 5G core 206 and two distributed units (DUs), including DU 212 and DU 214. The CU 210 provides control of the respective DUs, DU 212 and DU 214, in the 5G mobility network 202. The CU 210 is a logical node that performs a subset of eNodeB or gNodeB functions. The eNodeB or eNB or gNodeB or gNB is the network component of 5G mobility network 202 that communicates directly, wirelessly, with mobile devices such as the UE device 204. Such functions may include transfer of user data, mobility control, radio access network sharing, positioning, session management, for example. The CU 210 provides baseband central control. The CU 210 generally controls the respective DUs. The split of functionality between the CU 210 and DUs such as DU 212 and DU 214, is established by the network operator.
The DU 212 and the DU 214 are logical nodes that perform a subset of eNodeB or gNodeB functions. Each respective DU provides mobile radio communication service to user equipment devices such as the UE device 204 located in the respective cell served by the DU. Each DU including DU 212 and DU 214, is in communication with the CU 210. In some embodiments, each respective DU is a remote radio head (RRH) or remote radio unit (RRU), providing radio frequency (RF) communication with UE in each respective cell. Thus, DU 212 includes a RRU 216 and is also in communication with a remote RRU 218. Similarly, the DU 214 includes an RRU 220 and is in communication with a remote RRU 222. Each DU may communicate with the CU 210 using fiber optic cable or other means of data communication. Fiber optic cables are indicated in dashed lines in
The fronthaul network 208 of the 5G mobility network 202 further includes a low latency service 224. The low latency service 224 includes a CU 226, a DU 228 and a first optical line termination (OLT) 230 along with a second OLT 232. The first OLT 230 and the second OLT 232 are in data communication with an optical distribution network (ODN) 234. Further in communication with the ODN 234 is a first optical network unit (ONU) 236 and a first DU 240 along with a second ONU 238 and a first RU 242. A second radio unit (RU) 244 is in data communication with the first DU 240.
The OLT 230 serves as the service provider endpoint of a passive optical network (PON) 234. The OLT 230 operates to convert between electrical signals used by the service provider's electrical equipment and fiber optic signals used by the PON. Further, the OLT 230 operates to coordinate multiplexing between conversion devices on the far end of the PON, specifically the first ONU 236 and the second ONU 238 in the example of
The first ONU 236 and the second ONU 238 are used to terminate the fiber optic connector and demultiplex the optical signal. RU devices such as the first RU 242 and the second RU 244 operate to convert radio signals between an antenna and digital signal received at the ONU 238 and the DU 240, respectively. Connection between an RU and the ONU 238 and the DU can be optical or electrical such as Ethernet.
Components of the low latency service 224 are in data communication with the 5G core 206 to communicate data and control information. Further, the components of the fronthaul network 208 are in data communication with the SDAOC 210 either directly through fiber or electrical connections or indirectly through the 5G core 206.
As exemplified in
The fronthaul network 208 thus enables communication between the 5G core 206 and radio units such as RRU 220 in wireless communication with user devices such as UE device 204. The communication includes both user data communicated with the UE device 204 and control data for controlling components of the fronthaul network 208. The fronthaul network 208 is generally composed of optical elements for high speed, reliable communication. Multiple channels may be defined in the optical fibers connecting the components of the fronthaul network 208. As the mobility network 202 including the transport network changes and evolves to serve customers, the fronthaul network 208 evolves as well.
In a 5G optical fronthaul network such as the fronthaul network 208, several parameters can affect reliable communications. Such factors may include the distance between DUs, CUs and RUs. For example, the CU 226 and the DU 228 may be physically close together, but they communicate with RU 244 which in the example is too far away for reliable communication. In the example, a distance that is too great or too far may be determined in any suitable manner such as an error rate exceeding a predefined threshold because optical communications do not reach the far end of the connection. In another example, the DU 240 and the RU 244 are physically close, but they communicate with a CU 226 that is too remote for reliable communication. Again, remoteness may be determined according to any suitable standard or according to any suitable threshold such as a maximum available data rate, an acceptable error rate, a minimum throughput, etc. Distance between components may affect, for example, latency in communication between components or reachability of one component by another one. For example, in a small cell architecture, connection density is relatively high and many radio units may serve a particular area. However, the distance to each RU from a DU or CU may vary for each unit, which can affect the optical frequencies chosen for communication with the respective RU devices. In other areas, the connection density is lower and the choice of optical frequencies in a network is substantially different.
Other optical network parameters affecting reliable communications in the fronthaul network 208 include a non-uniform gain profile across frequencies for a portion of the network; absorption losses; scattering such as Rayleigh scattering and Mie scattering; a dispersion profile in which phase velocity of an optical wave varies with its frequency; and various optical fiber characteristics. When assigning a communication channel in the optical network, one challenge is finding a best spectrum location for the channel to ensure reliable communication from source to destination through all components of the network.
Moreover, the fronthaul network 208 can change over time. Such changes in optical characteristics can affect existing channels defined on the fronthaul network 208. Such changes can cause a delay or other issues when launching a new channel. For example, expanding capacity by adding more high-capacity channels can produce refractive index changes due to nonlinearity. Twists in the optical fiber can cause polarization mode dispersion. Laser characteristics can change over time, creating for example amplified spontaneous emission (ASE) noise.
Conventional networks such as the 5G mobility network 202 lack a capacity or capability to learn the characteristics of the entire network, including a WDM network. Further, conventional networks lack the ability to do analytics on network data to analyze and resolve problems in the network, such as low throughput, excessive latency or excessive bit error rate. Still further, conventional networks lack the ability to collect network parameters at run time and use that data to learn characteristics of a 5G optical fronthaul network. This learning can be used to make intelligent decisions about the network and its components when adding new channels, cutting the fiber, adding new fiber segments, etc.
In accordance with various aspects described herein, the SDAOC 210 can learn the parameters and characteristics of the fronthaul network 208. For example, the SDAOC 210 can learn the topology of the fronthaul network 208 as well as the physical characteristics of the fronthaul network 208 including the fiber connections between components. The SDAOC 210 can learn what frequencies to use for communication in the fronthaul network 208 as well as what type of modulation to use for a particular desired data rate. Further, the SDAOC 210 can store information about the physical characteristics, such as in a database at the SDAOC 210. The SDAOC 210 can then automatically determine if future demands of the fronthaul network 208 can be met by the current network and provide required modifications to meet future demands. Further, the SDAOC 210 can compensate for or correct changes or variations in such parameters or characteristics to improve reliability of communication in the fronthaul network 208.
In an embodiment, the SDAOC 210 includes a discovery engine to determine or discover the network topology for the network. For example, the discovery engine may identify node hops and other connections in the network. The discovery engine may further note neighbor information, including information about each network component it encounters (such as a CU, a DU or an RU) and detailed technical information about the connections available between the nodes. The discovery engine can get data from each node defining what links are available at the node and what connections are established between nodes. Once the information about network topology is gathered, the SDAOC 210 can form a model of the network.
Once the network and its topology and components have been modeled, the SDAOC 210 can make predictions and recommendations for the network based on inputs and requirements provided to the SDAOC 210. For example, the SDAOC 210 can receive or determine information about a network density and a customer's data rate requirement and, based on the collected information or the model of the network, recommend or specify a latency requirement or a frequency or modulation type for the particular customer served by the network. In another example, reachability varies with network parameters and the frequency being used for data communication. The SDAOC can receive as an input a desired or required reachability for a network segment and respond by recommending network parameters such as network topology, transmission frequency, modulation scheme and others to achieve that specified reachability for a particular network element or connection between two nodes.
A network operator associated with the system 200 can employ the SDAOC 210 to determine network parameters and develop recommendations from the SDAOC to satisfy design goals for the network. The network operator can then use the recommendations from the SDAOC to build out or modify the mobility network 202 and its components to achieve the desired goals. For example, some network connections may be upgraded from copper wire to fiber and optical connections. Some fiber connections may be improved, replaced or supplemented to increase throughput on a segment. Some network components such as a CU, DU or RU may be improved or supplemented to improve performance of network segments. In response to the recommendations of the SDAOC 210, the network operator may dispatch equipment, technicians or a combination to make necessary network modifications.
In the illustrated embodiment, the northbound adaptation function 252 enables data communication with any suitable business applications 252A. A northbound interface is an application programming interface that allows a lower-level network component to communicate with a higher level or more central component, such as a business system. For example, a business application 252A may provide command and control information to the SDAOC 210 to control the device or receive from the SDAOC 210 information about the fronthaul network 208 with which the SDAOC 210 is associated. The southbound adaptation function 254 may provide a communication interface with elements of the network infrastructure 254A. A southbound interface allows a higher-level component to send commands to lower-level network components. The network infrastructure 254A may include any network components such as CUs, DUs, RUs and other switches, routers and devices. Thus, the southbound adaptation may be configured to exchange data according to any suitable protocol such as Network Configuration Protocol (Netconf), a network management protocol; Openflow, a software defined networking standard: Transaction Language 1 (TL1), a management protocol; a command line interface (CLI), or other data communication format. Further, the network infrastructure 254A may include devices manufactured or provided by various vendors.
The model driven service abstraction 251 in embodiments operates as a model of the network under analysis, such as fronthaul network 208. The model driven service abstraction 251 is formed by collecting data by the components of the controller platform 250. For example, as the device discovery module 256 collects data about links and devices in the network, information about the links and devices is abstracted by the model driven service abstraction 251. Abstraction of the information may include any suitable processing including developing a functional model of cooperation among the links and devices of the network. In the example, the data of the model are segregated into a device layer, a network layer and a service layer. Data may be organized along other logic functional layers as well.
In the example, the SDAOC 210 including the model driven service abstraction 251 is a notification-based architecture. For example, if a node of the network infrastructure 254A changes in some way, such as if a node is added or removed from the network, information about the modification will be received by the SDAOC 210 at the southbound adaptation 254. The model driven service abstraction 251 responds to the received change by changing the model. The change to the model is notified by the notification module 264 to the topology module 258 and the topology defined by the topology module 258 is updated. If any change to the topology of the fronthaul network 208 is made, such as adding more RUs or adding a branch to the fronthaul network 208, that change is reflected in the model driven service abstraction 251 and thereby to the topology module 258.
The controller platform 250 in this example, includes a device discovery module 256, a topology module 258, a policy engine 260, a rule engine 262, a notification module 264, a 5G fronthaul spectral efficiency predictive engine 266, a 5G fronthaul spectral recommendation engine 268, and a train and test model service engine 272. Other embodiments may include additional, fewer or alternative features.
The device discovery module 256 operates to determine the contents and structure of a network such as the fronthaul network 208 of
The topology module 258 receives from the device discovery module 256 the information about the devices and links in the network. For example, the topology module 258 develops a model of the data connections between the devices of the network in conjunction with the model-driven service abstraction 251. Based on this information, the topology module 258 models the topology of the network, including modeling individual devices such as CU devices, DU devices and RU devices in data communication with a core network such as the 5G core network 206 of
The 5G fronthaul spectral efficiency predictive engine 266 receives analyzed data from the train and test model service engine 272. The 5G fronthaul spectral efficiency predictive engine 266 operates to predict the spectral response of the fronthaul network 208 including spectral efficiency for the given topology of the network. The policy engine 260 operates to enforce predefined policies on the network. The policies may be established by the network operator or by a standard such as the 3GPP standard defining 5G fronthaul technology and interoperability. The rule engine 262 operates similarly, to define and enforce network design and operation rules to ensure reliable operation. For example, standards such as those published by 3GPP define operational rules which must be adhered to for compliance with other equipment.
The 5G fronthaul spectral recommendation engine 268 receives information from the 5G fronthaul spectral efficiency predictive engine 266 including information about the predicted spectral response for components and links in the network. The 5G fronthaul spectral recommendation engine 268 operates to determine, based on the topology of the network, what spectrum should be tuned on the network to ensure the network will satisfy 5G specifications for fronthaul networks.
The SDAOC 210 may support the widest range of data rates in the network or portions of the network. Data rates used by the SDAOC may vary substantially. Required data rates may depend, for example, on the density of small cells used in the mobility network 202 and accessed by the fronthaul network 208. Based on those data rates, the capacity of the connections within the fronthaul network 208 are selected. Higher data rate requirements will in turn require larger capacity optical connections in the fronthaul network 208. Such data rates may range from 20 Mbps or less to 40 Gbps or more.
Further, the SDAOC 210 may support a wide range of modulation formats, including quadrature amplitude modulation (QAM), probabilistically shaped quadrature amplitude modulation (PS-QAM), and others as well including 16-QAM, 64-QAM and others. Further, the SDAOC 210 supports forward error correction (FEC) including standard FEC, enhanced FEC, ultra-FEC and adaptive FEC. The modulation technique is tied to the reachability of portions of the network. For example, if 64-QAM is used, the reachability for data is substantially reduced compared with 32-QAM. Still further, for communicating with other components of the system 200, the SDAOC 210 may communicate using Ethernet, optical transport network (OTN) protocols, fiber channels and others that may be suitable. The train and test model service engine 272 will predict spectral efficiency of a channel between the 5G CU and DU and the RU and make recommendations.
The train and test model service engine 272 operates to analyze the data collected about the network including network components and network links and select transmission parameters for a link. For example, the train and test model service engine 272 receives information about possible data rates in the link, available modulation techniques, available forward error correction techniques, along with other available information. In embodiments, the test and train model service engine 272 operates to select among possible data rates (such as 20 Mbps).
s or 40 Mbps), among modulation techniques (such as 16-QAM or 64-QAM), and among forward error correction rates and other factors as well. The train and test model service engine 272 selects the best values for rapid, reliable communication.
For example, the SDAOC 210 in general and the 5G fronthaul spectral efficiency predictive engine 266 operates to determine a number of parameters, as follows.
Spectral efficiency:
where M is number of symbols and N is dimensionality.
In embodiments, spectral efficiency may be calculated for all combinations of provisioning parameters.
Asymptotic power efficiency:
Average symbol rate:
Average energy per bit:
Attenuation:
where αdB represents signal attenuation per unit length in decibels and L is an optical length. pi is launch power and p0 is received power.
Stimulated Brillouin Scattering or SBS:
Stimulated Raman scattering or SRS:
where d and λ are fiber core diameter and operating wavelength, measured in micrometers. αdB is fiber attenuation in dB per kilometer and v is bandwidth of the injection laser. Computation of SBS and SRS help keep launch powers of channels in control to avoid these scatterings in fiber.
Rayleigh scattering:
where FR is the Rayleigh scattering coefficient, A is an optical wavelength, n is the refractive index of the medium, p is the average photoelastic constant, βc is the isothermal compressibility at a fictive temperature TF and K is Boltzmann's constant. So, for a constant refractive index, the remaining parameters are constant. The result therefore depends solely on the wavelength of light. Using the above relation, RC can be determined for each wavelength.
Material dispersion:
RMS pulse broadening is given by:
Dispersion in a single mode fiber:
Group delay for a light pulse propagating along a unit length of SM fiber may be given as:
to a first order.
Using these relations, a model such as the model-driven service abstraction 251 of the SDAOC 210 operates to predict parameters including a spectral efficiency of a channel between a 5G CU, DU and RU in a 5G fronthaul network and to make recommendations to improve parameters such as spectral efficiency. The model employs flexible modulation formats, data rates, forward error correction schemes and other communication features to tune a channel, its bandwidth and to optimize reachability in the network.
The data collected and modeled by the model-driven service abstraction 251 of the SDAOC 210 (
In particular use cases, the method 270 may be used to solve particular problems in active, installed networks such as the fronthaul network 208 of
In another user case, changing optical characteristics of a network such as the 5G optical fronthaul network may hinder launching new channels in a particular optical connection or may impact existing channels. For example, adding more high-capacity channels may cause a change in refractive index due to non-linearity effects. Further, polarization mode dispersion (PMD) may be caused by mechanical factors such as twists or bends in an optical fiber. Amplified spontaneous emission (ASE) noise may change due to increased amplification needs. Further, laser characteristics may change over time.
A method and device with aspects similar to those of the SDAOC controller 210 of
The method 270 may be performed by any suitable data processing system including a processor and memory. The memory may include a database or similar data storage component. The processing system may be located at any suitable location and may have access to components of the network under test, such as the fronthaul network 208 of
The method 270 includes a first step 274 of data generation, data gathering, data collection and computation. Step 274 may be a preliminary step or a precursor step. Step 274 may be performed in whole or in part from time to time as aspects or components of the network under test change, as traffic levels change, or for any other reasons.
At step 281, the SDAOC 210 or a similar device or process may determine a topology of the network. Step 281 may include retrieving information about components such as CUs, DUs, RUs, and other communication components operating on the network. This may be done in real time, while the network is operating and communicating data. For example, step 281 may include contacting a first network component and inquiring about active communication links of the first network component along with other components in communication with the first network component. Step 281 may include further polling components and connections to identify equipment including network connections of an optical network. The received information may be stored as received.
Step 282 may include capturing a network view. In an example, a model may be developed to define each component in the network and each component with which it communicates, as well as parameters of the communication link between the components. The network view may be prepared and saved as a model in which one or more components can be simulated to see effects on network behavior and performance.
At step 283, a first network element and a first network route in the model is selected. Any process or criteria may be used for selecting an initial element or route. A looping process will eventually select all elements for analysis.
At step 284. a set of parameters for the selected network element and the selected network route is selected. The selected parameters may be parameters related to communication by the selected network element and the selected network route. For example, the parameters may include a set of WDM channels used by the selected network element for communication over the selected network route. The parameters may include data rates, bandwidth, a gain profile, absorption losses, and other factors.
St step 285, a model such as the train/test model service 272 may be run. The train and test model service engine 272 or other model may operate in conjunction with a rule engine such as the rule engine 262 and a policy engine such as the policy engine 260 of the SDAOC 210 of
At step 287, the method 280 includes determining if there are more parameters to analyze. If so, control returns to step 285 to further run the train/test model for analyzing parameters for the selected network element and selected network route. The loop of steps 284, 285, 286 and 287 may continue until all network and communication parameters of the selected network element and the selected network route are analyzed.
At step 288, the method 280 includes determining if there are more network routes from the selected network element to analyze. In an example, a CU may be the selected network element. The CU may have as a first network route, a first optical connection to a first DU, a second network route including a second optical connection to a second DU and a third network route including a third optical connection to an RU. Each of these respective connections is considered and evaluated independently in the looping of step 283, step 284, step 285, step 286, step 287 and step 288.
Similarly, at step 289, the method 280 considers if there are more network elements for analysis. If so, control returns to step 283 where a next network element is selected along with one of the network routes associated with the next selected network element. Control proceeds through the various looping operations, running the test/train model for each connection for each component and storing results for each set of parameters. The process of method 280 continues until all nodes of the network have been analyzed and data stored.
At step 290, if a new network element is added, the process of method 280 is repeated to characterize the new element and any network connections established for the new network element. In embodiments, the entire analysis process of method 280 may repeated, or only portions of the model or data may be re-analyzed if they are affected by the network change. Similarly, if a network element or component is removed from the network, some or all of the steps of method 280 are repeated to maintain current data and models. Still further, if a component is replaced with another component, even a functionally similar component, some of all of the steps of method 280 may be repeated to maintain current data and models.
In some embodiments, step 291 may be performed and some or all of the operations of method 280 may be repeated periodically or as needed or on any other basis. For example, a laser in an optical connection may degrade over time or due to varying operating conditions. Equipment may vary over time and step 290 attempts to keep the model and the data on which the model is based fully up to date and to accommodate such changes.

In accordance with step 276, data from the detected topology may be provided to the model for analysis. Such data may be retrieved as stored, step 286,
Step 276 may include selecting parameters, based on the model, for a channel with optimal spectral efficiency for the particular connection between particular network elements. The spectral efficiency of a communication technology is the bit rate per unit bandwidth and includes all of the necessary overhead channels. Spectral efficiency in communications is the data rate that can be transmitted over a given bandwidth in a communication system. It is expressed as ‘bits-per-second per-hertz, (bits/s/Hz) and can be defined as the net data rate in bits-per-second divided by the bandwidth in hertz. In an example, an increase in demand for transmission capacity in optical fiber, such as the links connecting CUs, DUs and RUs in a 5G optical fronthaul network, requires an increase in optical spectral efficiency.
At step 278, the method 270 includes a process of making predictions and recommendations for the network based on results of data collection and analysis (step 274) and modeling (step 276). The model developed at step 276 may be used to predict and forecast future trends in a particular 5G fronthaul network. For example, training data for the network may include historical information about parameters, capacity, demand and other factors for the network. The ML model or DL model, using current data from the topology collected at step 274, may make a prediction about future network demands and requirements. Predictions may be used to modify the network, such as by adding additional components to accommodate future demand or expanding capacity of current network elements to accommodate future demand. As an example, the bandwidth of a particular link may be increased to increase capacity, or a single fiber connection may be upgraded with multiple fibers to increase capacity. Further, the network maybe segmented by installing more RUs to create more microcells and vary the traffic load within the existing network. In particular, using learning about network structure and operation over a period of time, step 276 may predict and forecast spectral efficiency for a channel between a 5G CU, DU or RU.
In another example involving the SDAOC 210 of
The ML model or DL model or other AI component in embodiments operates to optimize the reachability for each selected optical network route. Optical reach or reachability refers to the distance between an optical transmitter and optical receiver, or the length of an optical fiber or other connection, over which data may be reliably transmitted and received. Optical reach is the distance an optical signal can travel before needing to be regenerated. Longer optical reach corresponds with a smaller number of required regenerations and hence less equipment and lower operating costs. Reachability is a function of a number of parameters including modulation technique, number of channels present, and forward error correction techniques employed. Reachability is also a function of parameters such as gain profile, absorption losses, scattering and dispersion. The material properties of the optical fiber are also a factor in reachability.
Further, or instead, the SDAOC 210 may recommend the best or an optimal space in spectrum to launch a channel on the network, based upon results of the ML model as well rule-based policy engine at step 276. For example, when launching the best spectral efficiency channel, the SDAOC 210 or other device or process automatically pick the number of channels and location of those channels in the flex grid based upon distance. Flex grid refers to an arrangement in which channel spacing is flexible and not fixed. Due to non-linearities in the optical fiber and varying gain profiles, different channels will have varying properties. No two channels will have same gain profile and hence may have different reach. Using the collecting information and the ML model or DL model, the SDAOC operates to pick a best suited location in the flex grid for channels between two ends of network. The location in the flex grid or spectrum is defined by a wavelength and a spectral width for each wavelength.
In another example, a network component such as a CU, a DU or an RU may be operating outside of performance requirements. For example, a standard such as a standard published by 3GPP for network communication in a 5G fronthaul network may specify minimum performance parameters such as error rate or data rate. The ML model, DL model or other AI tool may determine, based on the network information collected at step 274, that the network component is failing to reliably meet the requirement of the standard. For example, the SDAOC 210, relying on the rule engine 262 or policy engine 260, may compare actual performance as reflected in the collected network data with a rule or policy describing the requirement of the standard. In response, the ML model or DL model develops a recommendation, based on all the information collected about the network, to modify physical aspects of the one or more components of the network to ensure the standard is met. In an example, the ML model may recommend a change to an existing channel, such as moving the channel to a different wavelength in the spectrum, to help the channel better meet the 3GPP requirements. The network operator may thereafter reconfigure one or more network components according to the modified parameters recommended by the ML model or other AI tool. Thus, the method 270 modifies spectrum usage and definition to resolve a functional or reliability problem in the network.
At step 279, the method 270 includes implementing the recommendation. For example, the SDAOC 210 may recommend that a new channel may be positioned at a particular wavelength v and at a particular spectral width. The SDAOC 210 may further recommend a particular data rate for the new channel, such as 1 Gbps. Moreover, the SDAOC 210 may recommend a particular error correction technique such as Enhanced FEC, and a particular data type, such as a fiber channel connection. The recommendations apply to a particular network route between a first network element, such as a CU, and a second network element such as a DU or RU. The recommendation is based on all the information collected about the physical network.
Based on the recommended parameters, a new channel is launched or defined for the specified particular network route, between the two specified network elements. The new channel may be tuned according to the recommended parameters. In some examples, new equipment may be positioned and activated in the network to launch the new channel. In some examples, the SDAOC may compute an impact of moving channels in spectrum. Some movements of existing channels may result in performance degradation for those channels. The SDAOC may define a maintenance window when action may be taken to redefine affected channels. During that time, the network components on each end of a network route are reprogrammed to define the preexisting channel at a new location in spectrum, with new channel parameters. The SDAOC may, in fact, define the reprogramming to occur automatically during a predefined maintenance window for the network equipment.
Accordingly, the system and method in accordance with the disclosure herein provides a unique method and apparatus for allocating spectrum in an optical network such as a 5G optical fronthaul network. The functions of the SDAOC described herein assist in the spectrum allocation. Further, the system and method simplify the problem of defining a hole in the operating spectrum for freshly launched channels. In other applications, the system and method maybe used in conjunction with a ML or DL model to defragment spectrum in a functioning network with minimal or no impact on existing traffic in the network.

In particular, a cloud networking architecture is shown that leverages cloud technologies and supports rapid innovation and scalability via a transport layer 350, a virtualized network function cloud 325 and/or one or more cloud computing environments 375. In various embodiments, this cloud networking architecture is an open architecture that leverages application programming interfaces (APIs); reduces complexity from services and operations; supports more nimble business models; and rapidly and seamlessly scales to meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations.
In contrast to traditional network elements—which are typically integrated to perform a single function, the virtualized communication network employs virtual network elements (VNEs) 330, 332, 334, etc. that perform some or all of the functions of network elements 150, 152, 154, 156, etc. For example, the network architecture can provide a substrate of networking capability, often called Network Function Virtualization Infrastructure (NFVI) or simply infrastructure that is capable of being directed with software and Software Defined Networking (SDN) protocols to perform a broad variety of network functions and services. This infrastructure can include several types of substrates. The most typical type of substrate being servers that support Network Function Virtualization (NFV), followed by packet forwarding capabilities based on generic computing resources, with specialized network technologies brought to bear when general-purpose processors or general-purpose integrated circuit devices offered by merchants (referred to herein as merchant silicon) are not appropriate. In this case, communication services can be implemented as cloud-centric workloads.
As an example, a traditional network element 150 (shown in
In an embodiment, the transport layer 350 includes fiber, cable, wired and/or wireless transport elements, network elements and interfaces to provide broadband access 110, wireless access 120, voice access 130, media access 140 and/or access to content sources 175 for distribution of content to any or all of the access technologies. In particular, in some cases a network element needs to be positioned at a specific place, and this allows for less sharing of common infrastructure. Other times, the network elements have specific physical layer adapters that cannot be abstracted or virtualized and might require special DSP code and analog front ends (AFEs) that do not lend themselves to implementation as VNEs 330, 332 or 334. These network elements can be included in transport layer 350.
The virtualized network function cloud 325 interfaces with the transport layer 350 to provide the VNEs 330, 332, 334, etc. to provide specific NFVs. In particular, the virtualized network function cloud 325 leverages cloud operations, applications, and architectures to support networking workloads. The virtualized network elements 330, 332 and 334 can employ network function software that provides either a one-for-one mapping of traditional network element function or alternately some combination of network functions designed for cloud computing. For example, VNEs 330, 332 and 334 can include route reflectors, domain name system (DNS) servers, and dynamic host configuration protocol (DHCP) servers, system architecture evolution (SAE) and/or mobility management entity (MME) gateways, broadband network gateways, IP edge routers for IP-VPN, Ethernet and other services, load balancers, distributers and other network elements. Because these elements do not typically need to forward large amounts of traffic, their workload can be distributed across a number of servers—each of which adds a portion of the capability, and which creates an elastic function with higher availability overall than its former monolithic version. These virtual network elements 330, 332, 334, etc. can be instantiated and managed using an orchestration approach similar to those used in cloud compute services.
The cloud computing environments 375 can interface with the virtualized network function cloud 325 via APIs that expose functional capabilities of the VNEs 330, 332, 334, etc. to provide the flexible and expanded capabilities to the virtualized network function cloud 325. In particular, network workloads may have applications distributed across the virtualized network function cloud 325 and cloud computing environment 375 and in the commercial cloud or might simply orchestrate workloads supported entirely in NFV infrastructure from these third-party locations.

Moreover, it will be noted that the disclosed subject matter can be practiced with other computer system configurations, comprising single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as personal computers, hand-held computing devices (e.g., PDA, phone, smartphone, watch, tablet computers, netbook computers, etc.), microprocessor-based or programmable consumer or industrial electronics, and the like. The illustrated aspects can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network; however, some if not all aspects of the subject disclosure can be practiced on stand-alone computers. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.
In one or more embodiments, information regarding use of services can be generated including services being accessed, media consumption history, user preferences, and so forth. This information can be obtained by various methods including user input, detecting types of communications (e.g., video content vs. audio content), analysis of content streams, sampling, and so forth. The generating, obtaining and/or monitoring of this information can be responsive to an authorization provided by the user. In one or more embodiments, an analysis of data can be subject to authorization from user(s) associated with the data, such as an opt-in, an opt-out, acknowledgement requirements, notifications, selective authorization based on types of data, and so forth.
Some of the embodiments described herein can also employ artificial intelligence (AI) to facilitate automating one or more features described herein. The embodiments (e.g., in connection with automatically identifying acquired cell sites that provide a maximum value/benefit after addition to an existing communication network) can employ various AI-based schemes for carrying out various embodiments thereof. Moreover, the classifier can be employed to determine a ranking or priority of each cell site of the acquired network. A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4 . . . xn), to a confidence that the input belongs to a class, that is, f(x)=confidence (class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to determine or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches comprise, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.
As will be readily appreciated, one or more of the embodiments can employ classifiers that are explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via observing UE behavior, operator preferences, historical information, receiving extrinsic information). For example, SVMs can be configured via a learning or training phase within a classifier constructor and feature selection module. Thus, the classifier(s) can be used to automatically learn and perform a number of functions, including but not limited to determining according to predetermined criteria which of the acquired cell sites will benefit a maximum number of subscribers and/or which of the acquired cell sites will add minimum value to the existing communication network coverage, etc.
As used in some contexts in this application, in some embodiments, the terms “component,” “system” and the like are intended to refer to, or comprise, a computer-related entity or an entity related to an operational apparatus with one or more specific functionalities, wherein the entity can be either hardware, a combination of hardware and software, software, or software in execution. As an example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, computer-executable instructions, a program, and/or a computer. By way of illustration and not limitation, both an application running on a server and the server can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can comprise a processor therein to execute software or firmware that confers at least in part the functionality of the electronic components. While various components have been illustrated as separate components, it will be appreciated that multiple components can be implemented as a single component, or a single component can be implemented as multiple components, without departing from example embodiments.
Further, the various embodiments can be implemented as a method, apparatus or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware or any combination thereof to control a computer to implement the disclosed subject matter. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device or computer-readable storage/communications media. For example, computer readable storage media can include, but are not limited to, magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips), optical disks (e.g., compact disk (CD), digital versatile disk (DVD)), smart cards, and flash memory devices (e.g., card, stick, key drive).

Processors can exploit nano-scale architectures such as, but not limited to, molecular and quantum-dot based transistors, switches and gates, in order to optimize space usage or enhance performance of user equipment. A processor can also be implemented as a combination of computing processing units.
As used herein, terms such as “data storage,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. It will be appreciated that the memory components or computer-readable storage media, described herein can be either volatile memory or nonvolatile memory or can include both volatile and nonvolatile memory.
What has been described above includes mere examples of various embodiments. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing these examples, but one of ordinary skill in the art can recognize that many further combinations and permutations of the present embodiments are possible. Accordingly, the embodiments disclosed and/or claimed herein are intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
In addition, a flow diagram may include a “start” and/or “continue” indication. The “start” and “continue” indications reflect that the steps presented can optionally be incorporated in or otherwise used in conjunction with other routines. In this context, “start” indicates the beginning of the first step presented and may be preceded by other activities not specifically shown. Further, the “continue” indication reflects that the steps presented may be performed multiple times and/or may be succeeded by other activities not specifically shown. Further, while a flow diagram indicates a particular ordering of steps, other orderings are likewise possible provided that the principles of causality are maintained.
As may also be used herein, the term(s) “operably coupled to”, “coupled to”, and/or “coupling” includes direct coupling between items and/or indirect coupling between items via one or more intervening items. Such items and intervening items include, but are not limited to, junctions, communication paths, components, circuit elements, circuits, functional blocks, and/or devices. As an example of indirect coupling, a signal conveyed from a first item to a second item may be modified by one or more intervening items by modifying the form, nature or format of information in a signal, while one or more elements of the information in the signal are nevertheless conveyed in a manner than can be recognized by the second item. In a further example of indirect coupling, an action in a first item can cause a reaction on the second item, as a result of actions and/or reactions in one or more intervening items.
